In the Legal Environment of Business course in a traditional undergraduate business curriculum, students are expected to acquire knowledge about many areas of the law and the application of law to business, society, and the international marketplace. Current concepts in undergraduate business education, such as ethics and sustainability, must also be included in one's classrooms. Some texts highlight issues with landmark cases or feature articles about businesses that have experienced high-profile legal and/or ethical dilemmas. Using high-profile cases and newsworthy business situations are useful in stimulating discussions. However, professors often struggle with keeping students engaged while in the classroom. Real-world examples in the classroom have the best pedagogical value because of their appeal to traditional college students. This article features TerraCycle, Inc., a business that can portray many of the legal principles taught in a Legal Environment of Business course, and this business is interesting to students. This business and its actual litigation with a competitor, coupled with hypothetical legal issues faced by typical businesses, can be used as a basis for discussion for the entire semester to illustrate many of the principles of a typical Legal Environment of Business course. Although this semester-long case study focused on this particular start-up business, any business of interest to students can be used. The authors discuss how to connect TerraCycle, Inc. to students and how it can be utilized for lessons in the classroom. (Contains 3 figures and 28 footnotes.)
